+Please note, newer versions of Windows (I believe starting with Win10)
+offer support for UCRT C-library in addition to traditional MSVCRT. As result,
+one may find 2 flavors of MinGW: one compiling against UCRT and another compiling
+against MSVCRT. Currently VIM comes with libXpm.a compiled against MSVCRT,
+so an attempt to build VIM against UCRT will fail with:

+    undefined reference to __imp___iob_func

+In which case, if one does not need support for XPM, then argument XPM=no can be
+added to make-command. If support is needed, then another flavor of MinGW must
+be used.

 Once you have downloaded the compiler binaries, unpack them on your hard disk
 somewhere, and put them on your PATH.  Go to the Control Panel, (Performance
 and Maintenance), System, Advanced, and edit the environment from there.  If

+Note, ARCH is necessary if you don't have the sed command in your $PATH. Just
+make sure that the correct value is used with ARCH. In the example above the

 After churning for a while, you will end up with 'gvim.exe' in the 'vim\src'
 directory.
 
+If you also want to get xxd.exe, install.exe etc. then just remove "gvim.exe"

 You should not need to do *any* editing of any files to get vim compiled this
 way.  If, for some reason, you want the console-mode-only version of vim (this
 is NOT recommended on Win32, especially on '95/'98!!!), you can use:
